I suggest we use Discord instead of Skype/WhatsApp, easy to set up, has mobile apps, way better for organising large number of people, setting up rooms with different topics (off-topic, attacks, announcements), you can ping any people, easier to share pictures etc, can get bots that will calculate stuff for u, dedicated voice channels you can opt into, runs better than skype, you can give people roles, and what they see and we can easily ping a certain role, e.g. Ocean 54 or something etc.
Just a suggestion tho wouldnt mind going back to the old school shiz
